WL20 Lanthanum Tungsten Electrode
Lanthanum Tungsten Electrode is well known for its good welding performance and its other advantage is its endurance of high current and low burn spoilage rate.
The lanthanated tungsten electrode has outstanding welding performance without radiation hazard. And its electric conductivity is the most close to that of 2% thoriated tungsten electrode. It enable welders to replace the thoriated tungsten electrode by lanthanated tungsten electrode easily and conveniently without any change in welding procedure. Therefore, lanthanated tungsten electrode is the most popular replacement of 2% thoriated tungsten in Europe and Japan.
